My mtDNA is in the K Haplogroup

Like thousands of other genealogists, I swabbed my cheek at a genealogy society meeting several years ago in a project conducted by the Sorenson Molecular Genealogy Foundation (SMGF). At the time, I sent a five generation pedigree chart to SMGF.

In early September, I received the invitation from GeneTree to receive my mitochondrial DNA (mtDNA) results from this test. I signed up with GeneTree, paid the $19.95 by credit card, and while I was on their site I uploaded a family tree of 644 individuals who are some of my ancestors. Today, I received my invitation via email to view my mtDNA results.

Hey - I'm a K! I'm not overly surprised of course.



The chart above is the distribution of the K haplogroup for mitochondrial DNA.

The web site says this about the K haplogroup:

"Mitochondrial haplogroup K is a sub-branch of lineage U. Haplogroup K is widely distributed across Europe and is found in about 6% of the population. Notable clusters occur in Ireland, Scandinavia, France, and regions of Northern Italy, where about 10% of the population carries this variation. Outside of Europe, haplogroup K is found in the Near East region (5-7% of the general population), the Northern Caucasus region (5%), Central Asia (4%) and North Africa (2-3%).

"Historically, the first appearance of haplogroup K was about 30-35,000 years ago, likely in the Near East region. Ancestors in this haplogroup expanded into Europe about 25,000 years ago, just before the last Ice Age.

"Haplogroup K splits into two subclades, K1 and K2. K1 represents about 89% of the haplogroup K population; K2 comprises about 11%. There are currently no regional correlations within the subclades; however, the haplogroup as a whole is found at high frequencies among the Ashkenazi Jews (32% of the haplogroup population). In particular, four Ashkenazi founding lineages were recently identified – three of these lineages were within haplogroup K. Only four ancestral women comprise these lineages and account for more than 40% of the current Ashkenazi population (about eight million people). These four lineages underwent major expansions throughout Europe within the past millennium. The most dominant of these lineages is a subvariation of K1 (named K1a1b1a), encompassing 19% of contemporary Ashkenazi Jews, approximately 1.7 million people."

I posted several matrilineal lines (that's the line of mothers) here, but I want to add my specific line below:

a) Betty Virginia Carringer (1919 San Diego CA - 2002 San Diego CA)
b) Emily Kemp Auble (1899 Chicago IL -1977 San Diego CA)
c) Georgianna Kemp (1868 Norfolk County, ON - 1952 San Diego CA)
d) Mary Jane Sovereen (1840 Norfolk Co ON - 1874 Norfolk Co ON)
e) Eliza Putman (1820 Steuben Co NY - 1895 Norfolk Co ON)
f) Sarah Martin (??) (1792 NJ - 1860 Norfolk Co ON)

My earliest known matrilineal ancestor was born in 1792, perhaps in Sussex County, New Jersey, according to the sparse records I (and others) have found. I'm not 100% sure that Martin is her maiden name.

My hope is that other persons have contributed their mtDNA to the SMGF study and that they share my matrilineal line.

I've read all of the educational material on the GeneTree site, and my conclusion is that this mtDNA test WILL NOT match me up with 100% accuracy to other family members. It only matches the Haplogroup, not specific markers the way the Y-chromosome DNA tests do. However, if there are persons with exact matches of the mtDNA, then it is possible that there is an mtDNA match within the last 500 years or so.

Future posts will show some screen shots of the DNA results, the mtDNA matches and the family tree aspect of www.GeneTree.com. GeneTree is a social networking site - you can invite family members to join and view the tree, add information and media, and see the DNA results.

I did the same thing and I am a "R" and unlike you, I was very surprised.

I just found out the other day that I belong to mtDNA haplogroup K!

I too was rather surprized to discover I was Ashkenazie Jew related to the "Levy" K

Im a K2 and have no idea where i come from. From my father's side im R1a. Unfortunately my mother's parents died very young so we dont know much about that part of our genealogical tree. Im born in Poland, now living in Norway:)
Cheers, cousins of Oetzi :)

I am also a K2 and my mother's ancestors came from Wales. Also a cousin of Oetzi the Iceman.

Another K2. My mother's female ancestry is in America from the late 1600s on and in UK/France before that. Not finding much specific info on K2.
